Thanks JenBell... my internet was not working for some time and my internet provider came up with a brilliant idea that i must re-install my OS!
So to have a stable system, i went back to Win XP! yeah... had to re-install all my softwares and office!
And the network is now working fine! Another friend of mine too told me about driver cleaner and he has been using it with good effect and worth the money. he was kind enuff to give me his bootable XP and SP3 with drive cleaner... got XP runnign stable. ran drivecleaner and removed all previous nvdia stuff.. installed latest 181.22 drivers for my 8600GT.
Ran one of the games that was stable so far.. Superbike challenge... as soon as i reach the rider selection screen and the preview of the bike is displayed... it freezes! damn!
then later, while watching a movie, the screen froze but sound kept playing.. after a few seconds, the video went at x3 speed and caught up with sound. I assumed some DVD read issue.
Sadly, later in the evening, yet another documetary i had recorded on my HDD behaved similarly! I checked the GPU temperature via Rivatuner 2.2 .. it was 60degC. And for the first time ever, i GOT the NVL error on XP!!!!!!!!!!!!!!!!!!
I tried flusing the 181.22 driver and installed 169.xx after a lot of restarts to make sure all was well..
Then tried playing SBK challenge.. same screen of rider selection.. FREEZE!!
i tried alt-tab and found temp 60degC!
Went to the electronics store next street and picked up a fan powered by MB.
Noticed that the 8600gt fan was way too slow and was hardly pushing any heat out! i was left with no efficient option but to fix the new fan on top of the existing fan. It was intended to force feed fresh air to the existing fan!
Was not smart.. but it worked. Both fans always ran at 100% speed. GPU temperature was stable at 55-58degC! I still get the bloody FREEZE with SBK game!
But it no more freezes with the movies atleast!
What is the REAL reason behind this ?? How can this be a mystery? I'm really frustrated with this card thats just completed 1yr and no more under warranty! i just dont feel like buying a new card..i'd rather pick up the new PSP 3004!
Else, next i'm going to remove the card and gonna runt he system with the on-board 512MB geforce6150... maybe i will try to overclock it and fry it! i'm pulling my hair off!
.. sorry for the long post!
